基本功能

1. 可實(shí)現(xiàn)對本地詞庫添加、刪除單詞功能
2. 可實(shí)現(xiàn)查詞功能，根據(jù)英文查釋義，優(yōu)先從本地詞庫查詢，如果本地詞庫沒有就自動網(wǎng)上查詢，并將其添加至本地詞庫
3. 可實(shí)現(xiàn)學(xué)習(xí)功能，每天50詞，可分批次學(xué)習(xí)，并有根據(jù)單詞選擇釋義和根據(jù)釋義寫單詞兩種學(xué)習(xí)方式
4. 可實(shí)現(xiàn)錯(cuò)誤回顧功能，在學(xué)習(xí)過程中出錯(cuò)的詞都保存在文件中，用于下次回顧
5. 可實(shí)現(xiàn)服務(wù)器多并發(fā)

涉及技術(shù)

1. C/C++
2. 文件操作
3. socket網(wǎng)絡(luò)編程
4. linux系統(tǒng)編程

需要工具

1. openssl
2. curl
3. 百度翻譯api

注：openssl和curl安裝在服務(wù)器（阿里云或騰訊云服務(wù)器）中，百度翻譯api可在百度翻譯平臺免費(fèi)申請標(biāo)準(zhǔn)版，好像有詞量限制，但也夠用了。具體安裝步驟網(wǎng)上教程很多，此處不做贅述。服務(wù)器詳情請參考https://blog.csdn.net/weixin_44690490/article/details/104342427

代碼邏輯

添加：定義一個(gè)結(jié)構(gòu)體，包含單詞和釋義兩個(gè)字符數(shù)組，并對其賦值，再將這個(gè)結(jié)構(gòu)體寫進(jìn)詞庫文件尾部

刪除：先將詞庫文件a更名為b，在讀取整個(gè)詞庫文件b，查找出需要刪除的單詞word，再創(chuàng)建一個(gè)與詞庫文件之前名稱a相同的文件c，此時(shí)c就成為了詞庫文件，再將word前后的數(shù)據(jù)寫進(jìn)文件c中，最后刪除文件b

學(xué)習(xí)：先讀取文件數(shù)據(jù)，在隨機(jī)抽取其中一個(gè)詞，按照需要的學(xué)習(xí)方式輸入答案，答錯(cuò)就將這個(gè)單詞保存在vector容器中，無論答錯(cuò)答對今日任務(wù)量都減一，在退出程序前將當(dāng)前完成量以及時(shí)間記錄在文件中，在下次啟動程序時(shí)判斷日期是否發(fā)生變化，是則將文件中的數(shù)據(jù)清零，否則保持不變。（具體整個(gè)學(xué)習(xí)方式的邏輯很簡單，沒有解釋點(diǎn)）

回顧：在學(xué)習(xí)中出錯(cuò)的單詞都記錄在vector容器中，在學(xué)習(xí)完后可繼續(xù)進(jìn)行錯(cuò)誤回顧，回答正確就將該單詞進(jìn)行尾刪，仍然錯(cuò)誤繼續(xù)存入容器中。如果學(xué)習(xí)完成后退出了程序，此時(shí)就將vector容器中的數(shù)據(jù)寫入文件中，便于下一次回顧。

查找：先讀取詞庫，如果在詞庫內(nèi)找不到你想要的單詞，此時(shí)判斷電腦是否聯(lián)網(wǎng)，已聯(lián)網(wǎng)就連接并將單詞發(fā)送給服務(wù)器，服務(wù)器通過百度翻譯api向百度翻譯發(fā)起請求，百度翻譯相應(yīng)后就將釋義返回給服務(wù)器，服務(wù)器再將其返回給客戶端

服務(wù)器多并發(fā)：創(chuàng)建一個(gè)線程p，主線程用于connect連接，p線程用于與客戶端的數(shù)據(jù)通信
